Abstract
The present invention discloses an LTE network selection method. In a process of implementing CSFB combined registration, an MME of a Long Term Evolution LTE network sends a location area identity LAI to UE, where the LAI includes a PLMN identity of the LTE network, so that after a circuit switched fallback-based voice session ends, the UE preferably returns to the LTE network according to the PLMN identity.
